Ampelopsin, also known as dihydromyricetin and DHM, when purported as an effective ingredient in supplements and other tonics, is a flavanonol, a type of flavonoid. It is extracted from the Japanese raisin tree and found in Ampelopsis species japonica, megalophylla, and grossedentata; Cercidiphyllum japonicum; Hovenia dulcis; Rhododendron cinnabarinum; some Pinus species; and some Cedrus species,[1] as well as in Salix sachalinensis.[2]

Hovenia dulcis has been used in traditional Japanese, Chinese, and Korean medicines to treat fever, parasitic infection, as a laxative, and a treatment of liver diseases, and as a hangover treatment.[3] Methods have been developed to extract ampelopsin on a larger scale, and laboratory research has been conducted with the compound to see if it might be useful as a drug in any of the conditions for which the parent plant has been traditionally used.[3]

Research

[edit]

Research suggests that DHM protects against DOX-induced cardiotoxicity by inhibiting NLRP3 inflammasome activation via stimulation of the SIRT1 pathway.[4]

In a trial of 60 patients with "nonalcoholic fatty liver disease," dihydromyricetin improved glucose and lipid metabolism and yielded potentially beneficial anti-inflammatory effects.[5]

A study of rats demonstrated pharmacological properties of DHM which suggest it would be a therapeutic candidate to treat alcohol use disorders.[6]

Dihydromyricetin shows poor bioavailability which limits its potential medicinal applications.[7]

Additional research is required before claims of human efficacy and application, necessary dosage, and solutions to poor bioavailability, are met with scientific validation.

Applications

[edit]

Ampelopsin is a versatile compound with a range of applications in health, wellness, and cosmetics, including:

  • Anti-Alcohol Intoxication: DHM is widely used in hangover remedies due to its ability to accelerate alcohol breakdown in the liver and mitigate alcohol-induced damage.[8][3]
  • Liver Protection: It helps in protecting the liver from toxins and promoting liver health.[9]
  • Antioxidant and Anti-Inflammatory: DHM has strong antioxidant and anti-inflammatory properties, contributing to its potential in preventing and treating chronic diseases.[10]
  • Cosmetic Applications: DHM is used in skincare products for its ability to protect skin from UV-induced damage and aging.[12]
